IMPROVEMENT IN FRAMES FOR BED-BOTTOMS.

Specification forming part of Letters Patent No. 128,504, dated uly 2, 1872.

SPECIFICATION.

- To whom it may concern:

Be it known that I, J OURGEN. WILLIAM CHARLES PETERS, of Chicago, in the county of Cook and State of lllinois, have invented certain new and useful Improvements in Bed- Bottoms, of which the following is a full, clear, and exact description, which will enable others skilled in the art to which my invention app ertains to make and use the same, reference being had to the accompanying drawing forming a part of this specification, and in which Figure 1 represents one corner of a bed-bottom provided with my improvements, the metallic plate being there represented upon the inside of the rail, and the end bar and oleat being shown by a vertical section across the same. Fig. 2 represents a like view, except that the metallic plate is there shown as attached to the outer side of the same rail; and Fig. 3 represents a side elevation of my improved bed-bottom, showing the position of one of the plates whenthe fabric is slack.

My invention relates to that class of bedbottoms -to which a fabric is attached for theter, in combination therewith, for the purpose of preventing bugs or other vermin from getting between those parts.

In the drawing, A represents the side rails of the bed-bottom. B B are metallic plates or levers attached to the ends of the side rails, either upon the inside or outside thereof, the plates B being rigidly attached to one end of the rails and the plates or levers B being pivoted to the other end, so as to beadjustable vertically, or in the arc of a circle about their pivots, and incapable of anyother movement thereon. O C are the pivotal bearings of the plates onlevers B. c is a perforation in the free lower end of the plates or levers B, and

c is a perforation in that end of the rails A, to which the plates or levers B are pivoted, the perforation 0 being in the arc of the circle in which the perforation 0 moves, when the plates or levers B turn upon their bearings. The plates or levers B B have a recess or socket sunken into the inner face of their upper extensions, and D D are the end bars resting therein, as shown in Figs. 1 and 2. E is a groove or channel in the outer longitudinal edge of the end bars. F is the fabric, the ends of which lie in the grooves E E, at which place the fabric is attached to the end bars by means of screws or similar fastenings, as shown in Figs. 1 and 2. The grooves or channels E E are filled with a suitable packing or cement, for the purpose of preventing bugs or other vermin from harboring about the screws and fabric therein, and such a packing or cement is especially serviceable when a woven-wire fabric is used. G G are cleats attached to the end bars, so as to protect the packing or cement in the groove or channel E and to retain it therein. The end bars may be secured to the plates. or levers B B by screws,

as shown at b b, Fig. 3. After the fabric is attached to the end bars and the latter to the plates or levers B B in the manner describedit being understood that the fabric is first made of such length that when slack it will be somewhat shorter than the distance between the extreme ends of the plates or levers B B when the latter are in the position shown in Figs. 1 and 2-it will be perceived that the pivotal plates or levers B will naturally occupy the position shown in Fig. 3.

In order to stretch the fabric, the plates or levers B are forced down until the perforations 0 are opposite the perforations c. The plates or levers B are then secured in that position by passing a bolt or pin through the perforations c c. The plates or levers B may be provided with more than one perforation,- o, or the rails A with more than one perforation, 0, so that the plates or levers B may be secured whenever the fabric is brought to a sufficient tension, or so that itmay be tight ened if it should become slack after being once stretched, without detaching it from the end bars.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

In combination, the side rails' A provided with one or more perforations, c, the pivoted plates or levers B adjustable in the arc of a circle and provided with one or more perforations, 0, the rigid plates B, end bars D provided with the groove or channel E, the cleats G and fabric F, all constructed and arranged substantially as and for the purposes specified.
